Hey guys! I am not sure if post goes under this thread or in the Motherboard section but as I am trying to learn from the OC masters here goes nothing
 
So I have a EVGA z87 Classified MB and I have paired it along with an i7-4790s. I know that the chip is locked and so with the help of a friend, I was able to manage a BCLK overclock of 103.5 which is already a really good number based on reading other posts on the internet of people not being able to get over 102. I think my friend and I pretty much hit the max of our knowledge. There are so many different settings on the board. I know if I could find a custom modified bios I could overclock this chip like any other K version chip but I haven't been able to find that bios.

Is there any suggestions that you guys have in terms of how I can maximize the potential of this chip? I know if it wasn't locked I would be able to get so much more out of it. Right now the PC crashes at anything over 103.5 BCLK because of the fact that my ram or something else cannot be pushed that far. It's just that I know that this CPU has so much more to give but it is limited because of the lock that intel has put on the chip. Is there any way to unlock the chip? I have it cooled by an EVGA CLC 280 and it runs so cool. After the BCLK overclock and running at 100% load, it maxes out at 70 C. Reading online the chip itself can go up to 110 before throttling so I know there is so much more this chip has to offer if it was not limited by the arbitrary lock that intel has applied.
 
Thank you guys for the advice and please let me know if I could provide any more information.

    No BIOS or socket/pin mod that I know of to unlock the thing..$344 and some change for a new i7-4790K at Newegg..I would shy away from buying a used one because it might be significantly degraded (electromigration) from somebody overclocking/overvolting it.
     
    TjMax is 100C, not 110C, for an i7-4790..That's the temperature at which each individual core will begin to throttle, if Thermal Monitoring hasn't been disabled (enabled by default) in the BIOS.

    You have probably maximized the potential at this point. When you do that, you have to pay attention to your RAM settings as well since the BLCK effects your RAM frequencies. You can spend countless hours on troubleshooting your maximum potential overclock with the BLCK adjustment and you might be able to squeeze a little more out of it... OR you could potentially run into a situation where your overclock is actually causing a decrease in performance and you basically have to keep everything at stock until you find more time to do it all again. If you continue with that, I would suggest messing with your voltages on the RAM.

    Not sure what your RAM frequency is, but I highly recommend looking into some 2400MHz DDR3 RAM. If you are only running 1600MHz, you would see a major improvement in your CPU performance.

    hmm okay what sort of differance would 2400 mhz ram make? And typically how much would be best to get, 16 or 32? also will I still be able to use my current 1600 mhz sticks?
     
    And is it worth the upgrade to the 4790k just for the sake of overclocking? Really I just like the system I have in terms of the motherboard and my gaming performance has not given me any issues so far.

    Also what is this I hear about hacked/modified bios which let you change the multiplier/overclock on a locked chip. Is this a thing? and if so where can I try it.
     
    I am also fully ready to upgrade the ram from 1600 to 2400 mhz but I honestly thought that difference was marginal. What type of difference should I expect?

    Nothing real-world noticeable..For a gaming rig, 16GB of RAM is considered minimum, but if you're system isn't currently using nearly all the RAM you have installed now, there's no point in adding more.
     
    You can install AIDA64 Extreme (30 day trial or pay), set it up to log System Memory Usage as well as Video Memory Usage and lots of other things, then leave it run in the background while you play games and do what you normally do on your PC, then check the log sometime later.
     
    No, you won't be able to use your 1600MHz sticks with 2400MHz sticks..They need to match in frequency and VDIMM (voltage).

    Then don't worry about getting a CPU with an unlocked multiplier, just leave it be if it performs/works good enough for you..Save up a couple grand or so for a new platform.

    It will also depend on your graphics card. I had a GTX 1080 when I was running my i7 4790K. I had some high latency 1600MHz RAM and upgraded to some low latency 2400MHz RAM, the difference was anywhere from 10-20% in the games I played... My frame rate was so much smoother after the RAM upgrade.
     
    I've seen a few i7 4770K's go for around $60 through my local facebook marketplace. Those might be worth looking into... But once you get into the 150+ range it's time to consider a newer generation CPU. After looking at prices on used DDR3 2400MHz RAM, it's not worth it. For some reason the value on that stuff has gone up recently. I would highly recommend looking at upgrading to a newer platform since DDR4 is getting so cheap. 

    You seem generally interested in overclocking, so my recommendation would be to pick up a i5 9600K and some nice 3600MHz RAM like this. Out of the box the i5 9600K will do 4.6GHz and can be overclocked to 5.0-5.2GHz. If you are not opposed to AMD, the Ryzen 5 2600X is also worth looking into, the price is pretty nice.

    RainStryke, thank you for the advice! Quick follow up, I can currently get a i5-4690k for 75 bucks brand new. Do you think this is worth it for the sake of attempting an overclock as compared to the 4790s? I took a look at 4770k's and they are not for sale around me on FB marketplace. I watched this video: https://www.youtube.com/watch?v=KzpYOHuSfaM&t=9s and it seems like essentially the same gaming performance at the 4790k.
     
    I'll be honest, there is no financial reason holding me back from upgrading my PC. It is really more sentimental since these components were the first gaming components I got while I was in college and It took alot of deliberation and assessing finances back then to pull the plug and pick up the PC. Essentially, another thing holding me back is the fact that my motherboard is sooo darn good. The EVGA z87 classified was probably one of the best motherboards you could have gotten in that era and I feel like I haven't even begun to explore its potential. I do plan to upgrade my PC but currently I feel like it is meeting my needs for the titles I am playing and I haven't played a game yet where I am getting horrendously low fps. So is a $75 dollar 4690k a quick cheap boost in performance? or a waste of 75 bucks because there will be titles coming out in the near future which would require more muscle?
     
    Also, this PC as it currently sits is more than enough for my gaming needs so far. On 720p and min settings (which I prefer from my Counter Strike days) I have been pushing nearly 200 FPS on COD:MW. I have a 240hz monitor so this type of high refresh rate is great. So I am wondering if an overclocked 4690k would help me push closer to that 240 fps mark in games such as this. my 4790s is pretty maxed out while running COD and so is my 980ti
     
    also, reading your signature, 5.2 ghz stable?? thats insane!!

    It's hard to say, if you get a decent one you might be able to get 4.7GHz or so out of it... On average those i5 4690K's max out around 4.5GHz on reasonable voltage. You will gain a little performance on the CPU clock, but lose some processing power. Lower resolutions like 720p and 1080p will see a lot more performance out of a higher clock speed, where 1440p is more reliant on the GPU. You did mention that you are all ready running out of processing power on COD:MW... So i'm not sure I would recommend the move to an i5.
     
    My i7 9700K does 5.2GHz on all cores with auto voltage... I messed around with it a little bit and found that I can put half the cores at 5.4GHz, but it's only stable long enough for a CPU-Z validation, not enough for a benchmark. My memory was able to hit 4536MHz for a benchmark though -- Once I get my new custom water cooling loop installed, I might be able to get a little more out of the CPU. The unlocked 9 series CPU's are pretty fun to play around with on the overclocking, they have a decent amount of headroom. My i7 7820X can do 4.8GHz, but it gets really hot even after deliding the processor.

    There is no magic BIOS that unlocks locked CPU , so sadly you likely already at the end of the road for 4790S. You could play with DRAM timings to squeeze few more points, but that's it. We focused on overclocking HEDT chips back then, so didn't really pushed to get unofficial OC stuff on Z87.

    If I were on the OP place, I'd buy used 4790K or similar chipie and have fun with it. With patience one could get such CPU for few beer bottles :)

    If you have question, please post in public forum. I do not reply PMs, so all in community can benefit the answer.
